There are a lot of temp sensors on this engine. I'll bet someone knows what all of them are or can help piece it together.

The temp sensors I'm aware of are:

- one post by the thermostat
- one post by the upper radiator hose
- two post by the upper radiator hose (105/115?)
- big one post on the head near the glow plugs (temp gauge)
- small one post on the head near the glow plugs

Thanks,
